Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494806, here are decompositions:

3 + 494803 = 494806
17 + 494789 = 494806
23 + 494783 = 494806
47 + 494759 = 494806
83 + 494723 = 494806
107 + 494699 = 494806
113 + 494693 = 494806
167 + 494639 = 494806

Showing the first eight; more decompositions exist.
